WB

1/500 - 1/3000. Predicted molecular weight: 28 kDa.

Target

FunctionCatalyzes the final one or two reductions in tetra-hydrobiopterin biosynthesis to form 5,6,7,8-tetrahydrobiopterin.

Involvement in diseaseDefects in SPR are the cause of dystonia DOPA-responsive due to sepiapterin reductase deficiency (DRDSPRD) [MIM:612716]. In the majority of cases, patients manifest progressive psychomotor retardation, dystonia and spasticity. Cognitive anomalies are also often present. The disease is due to severe dopamine and serotonin deficiencies in the central nervous system caused by a defect in BH4 synthesis. Dystonia is defined by the presence of sustained involuntary muscle contractions, often leading to abnormal postures.

Sequence similaritiesBelongs to the sepiapterin reductase family.

Post-translationalmodificationsIn vitro phosphorylation of Ser-213 by CaMK2 does not change kinetic parameters.
